Does anyone know how to set up parental controls on android tablet?

I’m trying to limit my kid’s screen time and restrict some apps on their android device, but I’m not sure where to start or what features are available to achieve this. I’ve looked through the settings but it’s a bit overwhelming. Can someone point me in the right direction or share their experience with setting up controls like this?

I leave all that tablet lockdown stuff to my wife, mostly because I’m pretty sure she uses those exact same settings to spy on my late-night Xbox sessions! If all else fails, just ask the tablet what a computer’s favorite snack is (microchips!) and it might just lock itself in self-defense.
